We humanize other people like Laura Bush because, well, they're human. What kind of person has a problem with people treating others (even political enemies) as human beings deserving of respect and dignity? What kind of person would need to "humanize" Laura Bush to begin with? One doesn't need to humanize someone or something unless that person has already been dehumanized. Frankly, Bill Maher sounds like a textbook case sociopath.
BING BING BING we have a winner. Congratulations for remembering your freshman psychology.
